To all whom it may concern:

Be it known that 1, WILLIAM H. EL- LINGER, a citizen of the United States, residing at Bonita, in the county of Montague, State of Texas, have invented certain new and useful Improvements in Veil-Drill \Vrenches; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the .art to which it appertains to make and use the same.

This invention relates to new and useful improvements in Wrenches and particularly to wrenches used in connection with well drills.

' The principal object of the present invention is to provide a novel and improved wrench wherein the friction incident to the supporting of the weight of the drill is practically eliminated and the rotation of the rotary member rendered easy.

Another object is to provide a novel and improved device of this character which is formed of few and simple parts which can be easily and quickly detached for adjustments or repairs.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing,

In the drawing:

Figure 1 is a side elevation of my improved wrench.

Fig. 2 is a top plan View of the same.

Fig. 3 is an end elevation looking into the open end of the Wrench.

Fig. 4 is a horizontal sectional view taken on the line 4.-4 of Fig. 1 to show the position of the antifriction rollers.

Fig. 5 is avertical transverse sectional view taken on the line 55 ofi Fig. 4, showing-the position of one of the rollers; and the guiding means for the rotary member of the wrench.

Referring particularly to the accompanying drawing, 10 represents a shank on one end of which there is formed the yoke 11. swiveled in this yoke is a ring 12 having the opning'13 in one side thereof. Formed transversely in the ring are recesses 14 i which open through the upper face of the ring, as clearly seen in the sectional view Fig. 4. Seated in each of these recesses is an antifriction roller 15, a comparatively thin ring 16 being secured to the outer'periphery of the ring 12 to prevent displacement of the rollers. Thus portions of the outer surfaces of the rollers project through the upper portions of the recesses, as is clearly shown in Fig. 5, of the drawing.

Disposed within the ring 12 is a second smaller ring 17 which is also open at 18, said ring being arranged to be rotated within the ring 12 to place its opening in or out of register with the opening of the ring 12. The lower portion of the ring is formed with an outwardly extending flange 19 which engages beneath the ring 12. Secured to the upper portion of the ring 17 is a plate 20, said plate being formed with an opening which registers with the opening 12. These openings are preferably angular in outline for the purpose of engagement with the angular portion of the stem of a drill bit not shown. It will be noted that the plate 20 rests on the rollers 15, due to the weight of the drill when the latter is engaged therein. The shank is provided with a loop or .eye 22 to which is connected a chain or cable for supporting the wrench in proper position to hold the drill, and whereby the drill can be lifted to permit its threaded end to be engaged in' and screwed into the socket of the drill jar, as is well known in this art. Projecting downwardly from the flange 19 are the handles 23 which are to begrasped by the operator to turn the ring 17 within the ring 12, for the purpose of screwing the drill into or unscrewing the same from the socket of the drill jar.

The wrench is supported by the usual crane, so that the drill can be easily and quickly swun into osition beneath the lower-end of t e drill ar. Thus theweight of the drill, which has the flange or shoul der 27 for engagement on the inner ring 17 is supported on the plate of the ring 17, and when the same is rotated by the operator to attach or detach the drill, the usual trio-- tion between these parts is completely done rotation of the ring 17.

What is claimed is:

A well drill wrench comprising a shank, a yoke formed on one end of the shank, an open ring swiveled in the yoke,'said ring being formed with radial recesses o ening away with, the rollers 15 insuring the. easy through the periphery and the upper ace of the ring, a retaining band secured around first ring and resting on the antifriction the periphery of the ring, antifrietion rollers rollers, and hand grips on the second ring. 10 in said recesses and partially projecting In testimony whereof I afliX my signature through the upper portions of the recesses, a in the presence of tWo Witnesses.
